Remember, in diffuse subendocardial ischemia with widespread ST-depression there may b e ST-E in lead s aVR and V1. There are well formed R-waves with good voltage/amplitude which is uncommon for ischemia. The ECG does not show any signs of ischemia. True Positive ECG#2 : Also sinus rhythm. There is ST depression in V1.

Well, don't we see diffuse ST Elevation in Myo-pericarditis (with STD in aVR)? Our chief of cardiology, Gautam Shroff, interprets it differently and thinks this is indeed ischemia. 109 (20):361-368, 2012 — CLICK HERE ). So this is STEMI, right? Which artery? There is ST Elevation in every lead except aVR (STD in aVR).

Occurrence of “J Waves” in 12-Lead ECG as a Marker of Acute Ischemia and Their Cellular Basis. Prominent J waves and ventricular fibrillation caused by myocarditis and pericarditis after BNT162b2 mRNA COVID-19 vaccination.
